To @Z5 07mm it may concern,.-

Be it known that I, JUDAH H. SEARs,'a citi zen of the United States of America, anda resident of Boston, in the county of Suolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Fleshing Hides, ofV which the following` is a specification.

This invention relates to improvements in hide-'working machines, and has for its object the production of a' machine in which the superliuous flesh may be removed from the.

hides by one knife-cylinder while another knife-cylinder is operating upon the opposite side for the purpose of unhairing the same.

It consists in certain novel features and arrangements of parts, which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter g'iven.

Of the drawings, Figure 1 represents a right-hand view of a machine embodyingthe Fig. 2 represents a central vertical section of the same, and Fig. 3 represents a front elevation of the left end of same.

Similar characters designate like parts throughout the several tigures of the drawings.

To support the working portion of the machine, a main frame is preferablyT provided made up of endframes 10 10 and tie-bars 11. At the front or feed side a bed-roll 12, preferably provided with a covering of rubber or like material, is mounted in the ends vof the levers 13, pivoted at 14 to boxes 15,`hav ing a vertical adjustment in the frames 1() by means of the adjusting-screw 16. The lower ends of the levers have pivoted thereto the threaded rods 17, having bearings at the rear of the machine in brackets- 18. The rods 17 have mounted thereon adjusting-nuts 19, be'- tween which and said" brackets 18 are interposed spiral springs 20,y which tend to force said levers 13 against theadjustable stops 21, Fig. 1, to limit theinward movementof the bedroll 12, but permit the same to yield outwardly when cooperating with the knife-cylinder 22, which is mounted in a pair of arms 23, pivoted to the upper end of the machine, and is preferably provided with spiral cutters. The tension of-the springs 2O may be regulated by adjusting the nuts19 on the rods 17. At the. pivotof said arms 23 is located a shaft 24, having' secured to one end agear 25 and a pulley 26, While on the other end is secured a pinion 27. Intermediate of the side frames 10 a driving-pulley 28 (shown'onl-y in Fig. 3) is mounted upon said shaft 24 to drive the same.` The gear 25 meshes with an interme.

diate gear 29,*mounted on one of the arms 23,'which in turnmeshes with a gear 30, on a hub of which, is mounted a gear 31, which meshes with a gear 32, secured to the knifecylinder trunnion 33 for the purpose of vrevolving the knife-cylinder at a high rate of radius-arm 40, the other end of which is pivoted to the driving-shaft 24. A gear 41 is mounted on the pivot 39 of the radius-arms 38 4() and meshes with and is driven by the gear 27 on the driving-'shaft 24, which motion is transmitted to a gear 42 on the shaft 37 for the purpose of revolving the feed-roll 36 and causing the hide to be fed when said roll is in position to coact with the bed-roll 12.

At 43 are pivoted levers 44, having mounted in one end thereof a supporting-roll 45. the other end of said levers are mounted rods 46, pivoted to the frames at 47 and provided with a coil-spring 48, the tension'of which may be regulated by means of the nut 49 on said rod 46. This roll 45 and the bed-roll 12 serve as a substantially stationary but slightly-yielding wsupport over which the hideis thrown ,to receive the fleshingtreatment to be hereinafter described. l

At the rear of the machine is mounted ashaft 50, having secured to one end thereof a gear 51 and on the other end a crank 52, each being provided with a crank-pin 53, which is connected by a link 54 to a knife-cylinder arm 23. A half-revolution of the crank 52 will cause the knife-cylinder to be moved toward the bed-roll 12, and the completionof the revolution of said crank 52 will cause said knife-cylinder to be moved away from said bed-roll into its non-operating position. The crank-pins 53 are also provided with a bearing 55 for the free end of the rods 56, pivoted to the feed-roll arms 35. The rods 56 pass freely through bearings 55 and are provided at their inner ends with nuts 57, which limit the movement of the arms 35 toward the hidesupporting rolls. The limitation of this movement-may be varied by an adjustment of the nuts 57. About said rods 56 are coiled spiral springs 58 between said bearings 55 and nuts 59, adjustable on said rods 56, thereby permitting the feed-roll to yield when coacting with the hide-supporting rolls 45 and 12. The gear 51 meshes with a gear 60, mounted upon a shaft 61, having an enlarged portion 62 and mounted in bearings 63. Upon the enlarged portion 62 is mounted a pulley 64, connected by a belt 65 to the pulley 26 on the shaft 24, by which motion is transmitted to said pulley 64 to cause it to continually revolve while the machine is in use.

The machine thus far described is the same as that which is shown in Letters Patent No. 736,278, issued August 11, 1903, to W. E. Lombard vand E. T. Luce, and the clutch and starting mechanism connecting the enlarged portion 62 with the treadle 80 used in this machine is the same as that which was described in th'e aforesaid patent. In order, however, to facilitate the work upon the hides and operate upon both sides, at the same time accomplishing the removal of the superuous flesh from one side while the hair is being removed from the other, a second knife-cylinder 90 is mounted beneath the bed-roll 12 in the end of a pair of arms 91, pivoted at 92, said arms 91 having pivoted to their opposite ends threaded rods 93, having bearings at the rear of the machine in brackets 94. rlhe rods 93 have mounted Athereon adjusting-nuts 95, between which and said brackets 94 are interposed spiral springs 96, which tend to force said levers 91 against the adjustable stops 97 to limit the inward movement of the knife-cylinder 90,-but permit the same to yield outwardly when cooperating with the bed-roll 98, mounted in an extension 99 to the levers 23, pivoted upon a shaft 24, upon which is mounted a sprocket-wheel 100, connected by a sprocketchain 101 to a sprocket-wheel 102 upon a shaft 103, upon which is mounted the knife-cylinder 90 and by which said knife-cylinder is revolved at a speed suitable for unhai ring, which is considerably less than the speed of the eshingcylinders 22.

The operation of the machine is as follows: The various parts of the mechanism being in the position shown in the drawings, a hide is taken by the operator and thrown over thc upper hide-supporting roll 45, so that its center is somewhat below the bed-roll 12. The operator then places his foot upon the treadle, depressing the same, which causes the shaft 50 to make a half-revolution, whereupon the crank 52 will move the feed-roll 36 into a position intermediate the supporting-rolls 45 and 12, causing the hide to be gripped thereby and fed outwardly. The same movement causes the ieshing-cylinder 22 to be moved into cooperating position with the bed-roll12 and the bed-roll 98 into cooperating position with the knife-cylinder 90, thereby causing both sides of the hide to be operated upon by knife-cylinders while being fed outwardly by means of the feed-roll 36. When one side of the hide has been fleshed, the operator depresses the treadle 80 to remove the feed-roll 36, fleshing-cylinder 22, and bed-roll 98 to the rear,.permitting the operator to remove the hide from the supporting-rolls 45 and 12 and reverse the hide and place the opposite end upon the hide-supporting rolls, so that the unfleshed and unhaired portions may bc subjected to the action of the knife-cylinders to complete the operation.

By producing a machine in which the iieshing and unhairing may be accomplished at the same time a great saving is made both in time and labor, which it is obvious is of great advantage.

Having thus described my invention, I. claim- 1. The combination of three pairs ofpivoted arms, a knife-cylinder and bed-roll mounted in the free ends of one pair of said arms, a knife-cylinder mounted in the free ends of another pair of arms, a bed-roll mounted in the free ends of a third pair of arms, means for moving said arms so that each knife-evt inder will cooperate with its coacting bed -roll, and means for feeding a hide between said knife-cylinders and bed-rolls.
